WITNESS/5S THE NORRIS PETER? 1,0 PHOfO-L/IHO wAwHNnmN n c PLOW. v a wiltain new and useful Improvements inPlows;

and I do hereby declare thefollowing to be a full, clear, and exactdescription of the invention, such as will enable,.othersvskilledconstructed according in the art to whichitappertains to make and usethe same.

This invention relates to plows,and meet the principal objects thereofis to provide a plow witha runner for supporting the plow atone endthereof, and for counteracting side draft.

Another object of my invention is to provide aplow, having a plow sharewhich may be easily and quickly secured or detached from the frog. ofthe plow. u

A still further object is to provide a plow which will be. simple,durable, eflicient in operation and inexpensive to manufacture.

With these and other objects in view, my invention consists in theconstruction, com bination and arrangement of parts hereinafter morefully described and claimed, and illustrated in the accompanying drawingin which like characters of reference indicate like parts throughout,and in which,

Figure 1, is a top plan view of a plow to my invention. Fig. 2, is avertical sectional. view taken. on a line 2-2 of Fig. 1, and drawn uponan exaggerated scale. Fig. 3, is an elevational I view looking from theland side of the plow. Fig. 4,is a bottom view of a portion of the plow.

In carrying out my invention I provide a solid frog having a verticalportion 5, and a top portion 6, formed integrally with the verticalportion and set at an angle thereto. The plow share 7 is provided at itsinner end with a forward extending point 8, and is in the general shapeof a wedge, having its under portion cut away as at 9, forming ashoulder 10, which is adapted to abut against the forward edge of thetop portion. 6 of the frog. The share 11 extends rearwardly from theshoulder 10, and abuts as at 12, against the front edge of the moldboard 13, which is bolted as at 14: to the portion 6 of the frog, thebolt heads being countersunk in the upper surface of the mold board.

Formed integrally with the plow share 7,

forward land side .15 to which is secured to the side 26, of thebrace,

A bolt 20, securesthe, a

the front end of the 7 vertical portion 5 of the frog, and the heads ofthe bolt 20 and bolts 19 are countersunk in the land side portions 15and .18 respectively. A plurality of bolts 21,.secure the plow share tothe upper portion 6 of. the frog, and the latter is. rimmed out as at22,. to form a recess for receiving'the nuts 23 of the bolts 21. Thevertical portion 5, of the frog is also rimmed out where the bolts 19and 20 extend therethrough.

Neat-the outer portion of the plow is situated a substantiallytriangular runner brace 24;, comprising an upper curvedside 25, a lowerstraight side 26, and a rear side a 27, the latter connecting the rear.ends of .85 thesides25 and 26... The side 25 is secured on the underface of the top portion 6, of the frog by means of bolts 28, whichextend through the mold board, frog, and the side 25 of the triangularbrace 2 1. As is shown, the brace 24, at the forward end thereof, isprovided with an offset portion 29, which has. its upper face mergingwith the upper face of the side 25, and which has its under facesituated below the plane of the side 26 95 and parallel therewith.Rearwardly of the offset portion 29, is situated a runner 30, which hasits under face in the same plane with the under face of the offset .29,and

by means of bolts 31, the latter having their heads countersunk in therunner 30. brace rod 32 extends from the side 27 of the brace across tothe vertical portion 5, of the frog, and is secured to that portion atthe rear end thereof, and serves to brace the runner.

When the plow is in use, the. runner 30 is adapted to bear against theground and to guide the plow forwardly, and as is obvious, the runnerwill bite into the ground. and thus counteract the side draft commonlythe 1 forward. edge of,
